Was ist RBF (replace-by-fee)?
A signalling mechanism that lets an unconfirmed transaction be replaced by a version paying a higher fee.
If a transaction is stuck because fees rose after it was broadcast, RBF lets the sender rebroadcast the same spend with a higher fee. Nodes replace the original in their mempool.
RBF is the reason unconfirmed transactions should not be treated as final. Zero-confirmation acceptance is a business risk decision, not a technical guarantee.
